PS: I worked at another department where they similarly misconfigured a SAN and made it highly vulnerable to multi-week outages due to even a single failed drive. I insisted they fix it, and my reward for this was seething hatred.
"You're just making us do extra work!"
"It's not a problem right now!"
"We have other priorities!"
Etc...
They literally refused to touch anything that's not on fire. Merely smouldering is "fine".
